The training data for the autoencoder of our DFE method is the University of Tennessee, Knoxville Face (UTKFace) dataset.
UTKFace is a large-scale face dataset with a long age span (range from 0 to 116 years old) [1]}.
It consists of \(24, 108\)  face images in the wild of humans of varying sex, age, and ethnicity, see Figure REF .
